Anti-Gβ5 Antibody

The Gβ5 (GNB5 guanine nucleotide binding protein (G protein), beta 5) is a G protein subunit present predominantly in the central nervous system. This protein appears to be expressed in two forms, one found in the brain of 39 kDa and one found in the retina of 44 kDa. It has also been found that Gβ5 associates tightly with RGS7, a member of the superfamily of negative regulators of G protein signaling. These complexes have been localized to most regions of the brain, whereas Gβ1-4 exhibit no observable colocalization with RGS7, despite their widespread codistribution throughout similar neuronal networks. This antibody is specific for a peptide sequence within the D1 blade which is not found in Gβ1-4.

~39 kDa observed. Uniprot describes 3 isoforms produced by alternative splicing at ~44 kDa, ~39 kDa, and ~31 kDa and this antibody is predicted to cross-react with all three.

Epitope: C-terminus

KLH-conjugated linear peptide corresponding to the C-terminus of human Gβ5.

Anti-Gβ5 is an antibody against Gβ5 for use in WB, ICC, IF.
